CVE-2015-0607

TITLE

Cisco IOS of Authentication Proxy Vulnerabilities that bypass authentication in functions

Trust: 0.8

sources: JVNDB: JVNDB-2015-001667

DESCRIPTION

The Authentication Proxy feature in Cisco IOS does not properly handle invalid AAA return codes from RADIUS and TACACS+ servers, which allows remote attackers to bypass authentication in opportunistic circumstances via a connection attempt that triggers an invalid code, as demonstrated by a connection attempt with a blank password, aka Bug IDs CSCuo09400 and CSCun16016. Cisco IOS is an operating system developed by Cisco Systems for its network devices. A remote attacker could exploit the vulnerability to bypass authentication by sending a specially crafted connection request. This may lead to further attacks. This issue is tracked by Cisco Bug IDs CSCuo09400 and CSCun16016
